umu-commander 2.1.0

umu-commander is an interactive CLI tool to help you manage umu.

umu-commander

umu-commander is a CLI tool to augment umu-launcher as well as help you manage its Proton versions.

This tool does not provide a centralised way of managing your games or utilise template umu-configs. See faugus-launcher or Nero-umu for something more akin to a games launcher, and umu-wrapper for templating functionality.

Proton versions can track and untrack directories, with the intention of safely removing them once no game depends on one.

Vanilla umu config files currently (06/2025) do not support setting environmental variables. This tool adds such functionality with an extra TOML table within said configs, see example_config.toml for an example.

Config

The configuration file lives at ~/.config/umu-commander.toml, which cannot be changed as of now. You can generate one by running the app by itself.

The config schema is as follows:

Name	Description
DB_DIR	Directory where the Tracking DB is stored.
DB_NAME	Tracking DB filename.
DEFAULT_PREFIX_DIR	Directory where umu-commander will search for WINE prefixes.
PROTON_PATHS	List of directories umu-commander will search for Proton versions.
DEFAULT_UMU_CONFIG_NAME	Default name of the umu config created using umu-commander create.
UMU_PROTON_PATH	Directory where umu-launcher downloads its UMU-Proton versions.
[DLL_OVERRIDES_OPTIONS]	TOML table where all possible DLL overrides are listed.
[LANG_OVERRIDES_OPTIONS]	TOML table where all possible LANG overrides are listed.

To add an extra DLL override option, add a line below the table in the form "Label" = "WINE DLL override string". Use the winhttp example as an example. You can add LANG overrides in a similar way.

Verbs

umu-commander needs one of the following verbs specified after the executable name:

Name	Description
track	Tracks selected config with the selected Proton version. Also removes it from any other tracking lists.
untrack	Removes the selected config from all tracking lists.
users	Lists which configs the selected Proton version is tracking.
delete	Interactively deletes Proton versions that are currently tracking nothing. Will not remove the latest UMU-Proton and Proton versions that haven't been used for tracking before. umu-commander will never delete anything without invoking this verb and confirming.
create	Creates an augmented umu config in the current directory. These configs are compatible with vanilla umu-launcher, although the DLL override functionality won't work.
run	Runs a program using the umu config selected.
fix	Attempts to fix invalid paths created from moving configs around.

Installation/Usage

Add umu-run to your PATH and then install with pipx by running pipx install umu-commander. After that you can use umu-commander by running umu-commander <verb>.

Return codes

Number	Name	Description
0	SUCCESS	Program executed as intended.
1	DECODING_ERROR	Failed to parse a file.
2	INVALID_SELECTION	User selected an invalid verb or there are no valid selections.
